CS-Lab / Re: CSMIO IP/A analog spindle RPM

« on: June 20, 2016, 03:44:49 PM »

Thanks Hood.
VFD is a KEB F5 with no easy way to get the current parameter setup so I don't know the frequency division to set exact spindle ratios.
Ordered a laser tach today to get actual spindle RPM then I can adjust the spindle ratio.

CS-Lab / CSMIO IP/A analog spindle RPM

« on: June 19, 2016, 08:51:24 PM »

Hi All,
Have the IP/A working good and finishing up the spindle feedback. Spindle controller has analog input and analog feedback but can't seem to get the spindle RPM DRO to display (always zero). Spindle controller feedback is wired to CSMIO analog input#1 and displays in the CSMIO plugin as getting analog signal.

Also, do I need a handheld laser tach to accurately calibrate the spindle with the RPM DRO or is there any other way to confirm?
Thanks

Safe Z is already set. Adding X,Y,Z move at the end of the script seems to resolve the issue - not sure why but it works for now.
Working on setting up auto tool length measurement after the tool change next.

Thanks for your help Hood, you seem to be on 24hr standby and always ready to help

Renamed M6End macro - no difference.
Cleaned up M6Start to remove unused macros and removed SetOEMLED(806, 1/0) commands since from what I read you cannot set OEM LEDs in VB script - new version attached. Same result as before.

Moving manually after tool change seems to fix random Z movement so it does seem to be script but not sure where

Macros/xml attached.
Its strange if I move slightly after tool change completes then G00 X50 works ok, but without slight movement same command also moves the Z axis up into the home/limit switch. Otherwise mill seems to behave. Thanks Hood for your continued help to everyone here.

Slight correction on the CSMIO firmware/driver tweaking missing - its been a while since I worked on the mill and was looking in wrong place  

I have G54 set and tool lengths in tool table. Only use T1-3 and they all work ok and sit at top of Z (-5mm off home) when complete.
When doing 'G00 X50' Z-DRO does move. Maybe tool length compensation has something to do with it.
If I move X away from the final tool change position seems to behave and Z behaves.

Hey All,
Only get to use my mill on occasion and recently started having issues with Z drifting up slightly on a G00 Xnn move. Have Mach3, CSMIO IP/A with Mitsu drives in analog mode. Recently updated the IP/A s/w. Heres the sequence:
   - home all axis to sit -5mm off home switches
   - give M6 T1, Z moves to home position (-5mm off home switch)
   - moves X,Y to T1 position
   - pickup T01 from table top ATC, Z moves up to home (-5mm off home switch) from M6 start macro
   - give G00 X50
   - X starts to move and Z drifts slowly up 5mm and triggers E-Stop going positive

This is repeatable unless I move to another X,Y position after the tool pickup complete and before Z move
Does this sound like a CSMIO issue with the Z drifting?

It seems the updated CSMIO IP/A firmware/driver does not have as many tweaking parameters as previous version.
Any ideas would be appreciated. Thanks.

Looks like I would be using the CSMIO based tool changer code. They have an example on their site that I will have to dig into.
VisualBasic and Cypress Enable - Oh joy !!!

XYZ axis are all configured and working with the SON signals going through a ULN2802A circuit for now. Have ordered Phoenix opto-isolated SSR DIN mount relay for permanent SON. Still tweaking parameters for optimal speed but working overall.

Spindle is working with analog signaling. Looking at the tool changer set up next. There is a fixed position 16 tool tray (2 rows of 8 ) with pressure switch for tool length measure on the tray and an air operated collet on the spindle. Googled around but didn't see any step-by-step guides so it looks like this will be challenging.
Any suggestions for tool changer macros ?

Appreciate all the help !

You are correct I connected enable (SON) outside the CSMIO for now (for testing) and assumed the DAC would have 0V when EMG signal is enabled. I'll fix the SON wiring.
If the EMG=off, SON=on, no active NC code, then servo should be actively locked in position by controller and have 0V on analog output. Correct?
